Abstract
PURPOSE: To obtain efficiently the sintered product without causing the waste of the amount of heat and the time, by sintering in the prescribed decompression chamber and, at the same time, carrying out in succession the heat treatment in the same decompression chamber.
CONSTITUTION: By heating the green compact W (not showed in the figure), for example, to 450°C in the preparatory heating chamber 1, the impurities and lubricant in the green compact are blown off. Then, by placing the preheated green compact W in the heating space 8 in the decompression chamber 3 which has been decompressed beforehand, raising its temperature and holding it at that temperature for an appropriate period of time, the sintering is carried out. Then, the sintered product W is brought out of the heating space 8, is placed on the conveyor 9 and is entered into the hardening tank 10. Then, the hardened product W is moved downward while being slided on the partition wall 11 and is placed under the normal pressure by being contacted with the outside air after the partition wall 11 has been closed. Basides, the above-mentioned oil cooling can be substtuted with the water cooling.
